Just to provide completion to this thread, I gave up on Haskell Windows web development after discovering that some important libraries like network-minihttp did not compile under Windows (and I could never get FastCGI to work properly either, although it did compile). I'm now developing using Fedora running in VirtualBox. It took several hours to get the Haskell Platform installed properly under the Fedora version I'll be deploying to (Fedora 9), but now everything seems fine, including FastCGI. Since my end goal is to deploy to Fedora 9 in any case, this seems a good solution. Kevin --- On Thu, 11/26/09, Michael Snoyman wrote:

Also, you could run a FastCGI script in a different language (Perl?) and see if that works. I can't say, however, that I've even used FastCGI on Windows.

Just to add more detail:

I am running Apache 2.2.9. The message I mentioned appeared in the Apache error log file when running the sample Haskell FastCGI scripts under localhost with mod_fastcgi.

I understand that there are some problems with mod_fastcgi and Apache 2.2.9, so I downloaded the Apache 2.2.9 version of mod_fcgid from here:

http://www.apachelounge.com/download/

and tried that instead.

I no longer get the error message I mentioned before, but instead get:

[Thu Nov 26 08:44:30 2009] [warn] mod_fcgid: read timeout from pipe

[Thu Nov 26 08:44:30 2009] [error] [client 127.0.0.1] Premature end of script headers: test2.fcgi

Any suggestions?

I'm attempting to get FastCGI working

...

with Haskell under Windows XP.

...

...

However, all the sample code I've tried always fails with:

...

...

user error (FCGX_Accept_r failed with error code: -9999)

...

unknown listenType (0)

...

...

Has anyone seen this before? Any ideas on what I could try

...

to get this to work?
